Fix PR gas/22738 (.dc.a directive has wrong size on SPARC 64-bit).

The .dc.a directive has wrong size (32 bits) on SPARC 64-bit because
the assembler sets the correct BFD architecture only at the very end
of the processing and it's too late for the directive.  It's fixed by
defining TARGET_MACH and making it return a sensible default value.

gas/
* config/tc-sparc.h (sparc_mach): Declare.
(TARGET_MACH): Define to above.
* config/tc-sparc.c (sparc_mach): New function.
(sparc_md_end): Minor tweak.
ld/
* testsuite/ld-elf/pr22450.d: Remove reference to SPARC64.

That's not entirely true since sparc_md_end will set the correct architecture:

(gdb) bt
#0  bfd_default_set_arch_mach (abfd=0x769d20, arch=, 
mach=) at /home/eric/cvs/binutils-gdb/bfd/archures.c:976
#1  0x00428774 in sparc_md_end ()
at /home/eric/cvs/binutils-gdb/gas/config/tc-sparc.c:1187
#2  0x00403da6 in main (argc=2, argv=0x754350)
at /home/eric/cvs/binutils-gdb/gas/as.c:1288
(gdb) p *stdoutput->arch_info
$7 = {bits_per_word = 64, bits_per_address = 64, bits_per_byte = 8, 
  arch = bfd_arch_sparc, mach = 7, arch_name = 0x514dd3 "sparc", 
  printable_name = 0x519135 "sparc:v9", section_align_power = 3, 
  the_default = 0, compatible = 0x433f90 , 
  scan = 0x433b90 , fill = 0x433f60 , 
  next = 0x519440 }

but it's indeed too late for the .dc.a directive.
